How do I use the snap tool without having my objects intersect?
I find using closest edge or vertex is much easier to control than &quot;snap to closest face&quot;. You can place your mouse cursor near the edge/vertex you want to snap to and an orange circle lets you know where it is about to snap to. If it is a complex model with lots of close together edges and vertices it helps to zoom in as much as possible to make selecting the correct snap point easier.
Also, selecting &quot;closest&quot;, &quot;center&quot;, &quot;median&quot; or &quot;active&quot; can yield dramatically different results depending on your geometry. Its not a bad idea to try each setting when you first use a new tool to see how each performs differently.
